Re: [Elecraft] Neoprene Ring for K3

[Fred Jensen]

I have yet to get mine on ... no time and a technical difficulty in my 
mind ... however it's only 16 bucks.  I can spend more than that [and 
often do] with jock granddaughter [softball, volleyball] and boyfriend 
[football, basketball] at Ernie's All-American Hamburgers.


Even though I don't have it on the knob yet, I can tell that it is a LOT 
less slippery than the original under my fingers, and a bit thicker.  It 
also has a slightly raised section of larger "blocks" next to the radio. 
 I can only simulate how it will be when I get it onto the knob, but 
right now, it looks really good for me.

And if you ever do need to remove the knob, the set screw hole is under the
ring (or as some say 'tyre')

No set screw Fred. It sits up against a shoulder at the rear of the metal
knob. Just loosen it up from that shoulder and it will slip right off.

Re: [Elecraft] K3 Neoprene ring

[Chortek Bob via Elecraft]

Hi Fred,
No need to remove the knob. 
Just remove the existing rubber ring (use a small toothpick or something that 
won't scratch the knob)to make space between the knob and rubber until you can 
grip the rubber) and replace it with the new one.  That's how I did it.
Good luck,
Bob/AA6VB

[Elecraft] OT: W8FGU Enclosure & Shipping Changes

[Dave W8FGU]

As I posted last week, the price increases for my enclosure line will go 
into effect tomorrow, March 5th. I've resisted the increase for as long 
as I could and have not raised my prices in over 3 years. But alas, I 
cannot ignore my supplier price increases any longer.


I've also implemented weight and zone based shipping now. As well as an 
option for Standard Domestic (First Class Package Service) for single 
enclosure orders (16 oz or less) for a $5.65 flat fee for any domestic 
USPS zone.


For international customers, I've created (painstakingly) PayPal tables 
for both USPS Priority Mail International and First Class International 
pricing, for any country that the USPS provides shipping services.


All customers should now see two shipping options when checking out of 
the shopping cart. If you use the shipping estimator in the cart, it 
will most likely give you the cheapest price, but you will still have 
the option to select your preference before concluding your purchase (I 
don't have any control over this).


Please see my site for more details: http://w8fgu.com

Thanks again for the bandwidth and if you have any questions or concerns 
please contact me at dave at w8fgu dot com.


73,
Dave W8FGU

[Elecraft] P3 - Control from Python Gui

[a45wg]

Fellow Hams,
I have found time to update the P3 Controls - it is now fully GUI - and 
you can have any type of split (not negative !!) with a p3 bandwidth of up to 
10Khz, with the carrier at any offset you want from (0-5khz)

The code is in my github page at 
https://github.com/timseed/Elecraft-K3-Pan-Pile-Up-Settings 


It now however requires QT5 (which can be troublesome on certain days 
of the week to install) - but once installed - a few more packages (numpy, 
pyserial, guidata) and you are done.

If anyone requires any assistance with this - please PM me off-list.

Regards

Tim - A45WG

[Elecraft] Tnx RFI filter recommendation

[brian]

Somebody recommended a line filter Schaffner FN2010-20-07 for a noisy 
appliance.  Thank you.


We moved to a new QTH with relatively new appliances.  Fortunately the, 
HVAC, dryer and washing machine are RF quiet despite variable speed DC 
motors.


The high end Kitchenaid dishwasher was another story. (High price = high 
RFI ?) It generated noise 30 db above ambient.  Looking at the 
schematic, it's clear why.  Lots of triacs and motors with speed 
controllers.  No line filtering except for one ferrite bead (one turn) 
wound around the hot side of the AC line.


We first tried ferrites on most leads.  This helped about 10 db.  Not 
enough.


Then we went to the Schaffner filter with the ferrites.  It dropped the 
noise to 1-2 db above ambient and occasional spikes a few dB higher. 
Nice.  Now to go back and try and recover some of the ferrites.


I don't know what the incremental cost of such a filter/filter design 
would be.  For a $1K+ diswasher, it should have been included.

couple of heavy larger ones in the junk box and the difference is hard 
to miss.  The cable from it is the radiator of course, a BC band radio 
tuned to a clear spot [preferably at the high end] will usually show a 
distinct increase in noise as you move it up the cable.


I was choking a 4 A feed to the wireless equipment and used a couple 
of 3 1/2" OD [or so] toroids that N6XI gave me.  Consulting the K9YC 
recipe, I wound 12 turns of Radio Shack red-black pair on one,


For the record, ALL zip cord, including the red/black stuff and the 
glorified zip cord sold as super exotic speaker wire, is TERRIBLE for 
RFI. Twisted pair is FAR superior, and should always be used in any 
situation where there is RFI. This has been well known for at least a 
century -- in the early days of telephony when the only noise source was 
50/60 Hz power and telephone wiring often ran on the same poles as power 
wiring, the only crosstalk prevention was a crossover of the telephone 
pair at every other pole.


and as many turns as I could get in one layer on the other, wired them 
in series and then stacked them using zip ties.  My theory was that 
the one with lots of turns would get the 160-80 m stuff and the 12 
turns would get 40-30-20. 


Max possible turns is about right for 160M on #31, 8 turns is about 
right for 40-30-20. This is for a 2.4-in o.d. toroid.


They went right at the Chinese RPOJ power supply in the 24 VDC cable. 
I don't know the mix but I think probably 34 or 43, I think they were 
part of a group buy by the contest club.


All our group buys have been #31.



My experience with the small clamp-ons has been poor, unless you get 
several turns of the cable through it, and even then I don't think 
there's enough permeability in the magnetic circuit to do much.  It's 
pretty hard to find linear wall warts these days.


Right. A choke without enough wound turns is a waste of time and money. 
BUT inductance is proportional to the length of the cable path through 
the ferrite, and the clamp-ons are much longer than the toroid, so fewer 
turns are "right" with clamp-ons as compared to toroids. Roughly half 
the number of turns is a good rule of thumb. 5 turns is a  good starting 
point for a #31 clamp that's about 1-inch long for 40M - 10M.  2 turns 
is about right for 6M, with several of these 2-turn cores in series 
along the coax.


I'm currently working on a step-by-step tutorial on chasing noise, and 
with some detail about different noise sources. First publication will 
be in the next issue of NCJ.


73, Jim K9YC

[Elecraft] OT: FLDIGI

[Jim Sheldon]

I have what I need coming from a very reliable source.  Thanks to 
everyone who replied.


Jim - W0EB

Does anyone have the older FLDIGI install files dating from before they 
took it off the internet that they could send me?
Contact me off the reflector please.  I don't want to get a FLDIGI 
pro/con thread started here, just looking to find the program.

What's currently available through Source Forge is not what I need.

Re:

" QRN, not QRM
I thought QRN was exclusively atmospheric noise.  Perhaps we need a new

We do have one...in the 'old abbreviations books' -- it's QRNN.  (Young

Re: [Elecraft] [KX3] How to use manual notch in SSB mode

[David Anderson]

Thanks for that workaround Steve, I must give it a try here. 

I can't understand why Elecraft don't give us the option of manual notch on SSB 
on the KX3, as I find the auto notch doesn't always lock onto weak but annoying 
heterodynes but could be easily notched out manually.
